Sokhadze1,3 1Department of Bioengineering, University of Louisville, Louisville, Kentucky, USA 2Department of Pediatrics, University of Louisville School of Medicine, Louisville, Kentucky, USA 3Department of Psychiatry and Behavioral Sciences, University of Louisville School of Medicine, Louisville, Kentucky, USA Children diagnosed with an autism spectrum disorder (ASD) often lack the ability to recog- nize and properly respond to emotional stimuli. Emotional deficits also characterize chil- dren with attention deficit/hyperactivity disorder (ADHD), in addition to exhibiting limited attention span. These abnormalities may effect a difference in the induced EEG gamma wave burst (35–45 Hz) peaked approximately 300–400 ms following an emotional stimulus. Because induced gamma oscillations are not fixed at a definite point in time post- stimulus, analysis of averaged EEG data with traditional methods may result in an attenu- ated gamma burst power. We used a data alignment technique to improve the averaged data, making it a better representation of the individual induced EEG gamma oscillations. A study was designed to test the response of a subject to emotional stimuli, presented in the form of emotional facial expression images. In a four-part experiment, the subjects were instructed to identify gender in the first two blocks of the test, followed by differentiating between basic emotions in the final two blocks (i.e., anger vs. disgust). EEG data were collected from ASD (n ¼ 10), ADHD (n ¼ 9), and control (n ¼ 11) subjects via a 128-channel EGI system, and processed through a continuous wavelet transform and bandpass filter to isolate the gamma frequencies. A custom MATLAB code was used to align the data from individual trials between 200 and 600 ms poststimulus, EEG site, and condition by maximiz- ing the Pearson product–moment correlation coefficient between trials. The gamma power for the 400-ms window of maximum induced gamma burst was then calculated and com- pared between subject groups. Condition (anger/disgust recognition, gender recogni- tion)  Alignment  Group (ADHD, ASD, Controls) interaction was significant at most of parietal topographies (e.g., P3-P4, P7-P8). These interactions were better manifested in the aligned data set. Our results show that alignment of the induced gamma oscillations improves sensitivity of this measure in differentiation of EEG responses to emotional facial stimuli in ADHD and ASD.

Research suggests that abnormalities of elecltroencephalogram (EEG) gamma oscillations may provide a biomarker of the condition. In this study, envelope analysis of demodulated waveforms for evoked and induced gamma oscillations in response to Kanizsa figures in an oddball task were analyzed and compared in 19 ASD and 19 age/gender-matched neurotypical children. The ASD group was treated with low frequency transcranial magnetic stimulation (TMS), (1.0 Hz, 90% motor threshold, 18 weekly sessions) targeting the dorsolateral prefrontal cortex.

  • Neurotribes: the Legacy of Autism and the Future of Neurodiversity Pdf, Epub, Ebook
    NEUROTRIBES: THE LEGACY OF AUTISM AND THE FUTURE OF NEURODIVERSITY PDF, EPUB, EBOOK Steve Silberman,Oliver Sacks | 544 pages | 20 Oct 2015 | Avery Publishing Group | 9781583334676 | English | United States Neurotribes: The Legacy of Autism and the Future of Neurodiversity PDF Book The book portrays Kanner as a swindler, a Doctor that had no business being a serious player in child psychology, and someone who knowingly, maybe even maliciously, ignored Hans Asperger's writings on the "normal" side of the autistic spectrum to promote his own career. As an autistic adult with an autistic son I was sickened by the book, the therapies, the history. But the autism spectrum encompasses a broad range of capabilities, and high-end functioning autistic people are able to get along just fine. Apparently research has tended to treat it as a disease needing a cure, rather than as a different way of being that requires support. It seems we are in a vicious circle with these kids that aren't quite like us: we pathologize their personality--we define it as autism and then try to cure it. From Wikipedia, the free encyclopedia. As a history of autism and its diagnosis, treatment, and social acceptance, this is a solid book. This handsome lifetime edition of the beloved and bestselling inspirational classic features the complete original text plus a special bonus work: Eight Pillars of Prosperity, James Allen's final and most practical work. The reader who makes it all the way through the book This book provides a thorough account of the troubled history of the psychiatric understanding of Autism Spectrum Disorder this includes Asperger's syndrome.

  • Adam Feinstein
    Neurodiversity: The cases for and against Presentation by ADAM FEINSTEIN Exeter University, December 11, 2017 Johnny and Adam ‘Neurodiversity’ • Term coined by Judy Singer in 1988. • Popularised by Harvey Blume, writing in The Atlantic in 1998: ‘Neurodiversity may be every bit as crucial for the human race as biodiversity is for life in general. Who can say what form of wiring will prove best at any given moment? Cybernetics and computer culture, for example, may favour a somewhat autistic cast of mind.’ Three fundamental principles: • Neurodiversity is a natural and valuable form of human diversity. • The idea that there is one ‘normal’ or ‘healthy’ type of brain or mind, or one ‘right’ style of neurocognitive functioning, is a culturally constructed fiction, no more valid (and no more conducive to a healthy society or to the overall well-being of humanity) than the idea that there is one ‘normal’ or ‘right’ ethnicity, gender, or culture. • The social dynamics that manifest themselves in relation to neurodiversity are similar to the social dynamics that manifest themselves in relation to other forms of human diversity (eg. diversity of ethnicity, gender, or culture). These dynamics include the dynamics of social power inequalities, and also the dynamics by which diversity, when embraced, acts as a source of creative potential. The case for neurodiversity in the workplace: Hans Asperger (1906-1980) Hans Asperger (1944): ‘We can see in the autistic person, far more clearly than with any normal child, a predestination for a particular profession from earlier youth. A particular line of work often grows naturally out of his or her special abilities.’ SAP’s ‘puzzle piece’ metaphor: People are like puzzle pieces, irregularly shaped.
